<p>A method for measuring heat and pressure characteristics of a fusing contact arc or nip formed between heat and pressure fusing rolls for fusing powder images onto a copy sheet. A toner powder pattern is formed on a first strip of paper. A second strip of paper is placed in overlying position with the first strip of paper to form the nip measurement device. The two strips are positioned between the opened nip of heat and pressure fusing rolls which are then closed for a predetermined time. Upon separation of the rolls the two strips of paper are removed and stripped apart. A portion of toner powder pattern is offset from the first strip of paper onto the second strip of paper indicating immediately heat and pressure charactersitics of the fusing nip.</p> |
